To all whom 'it' may concern Be it known that` I, ADoLPH A. CAInLn, a citizen of the United States, and a resident of Detroit. in the county of Wayne and l the load is removed from the scale platform,

`or when the load .on the platform is increased after the parts are in position for weighingthereby preventing the weighing of more than one 'load upon the insertion of a single coin.

To accomplish the object first mentioned, this invention comprises' an l auxiliary mounting for the scale platform, and an auxiliary system of levers and rods connected thereto, one of the rods being adapted to be thrown up under the main beam wheny ever a load is placed upon the platform.

`The invention further comprises a com operated mechanism whereby two members of this system of rods and .levers are connected .to each other upon the insertion of a coin.

To accomplish the' second object mentioned, this invention comprises a Vmain connecting bar having a spring attached thereto, t-he spring being tensioned by the load on the load receiver, in this case-,a platform,

and certain mechanism whereby the tension of the spring is utilized, upon the load being decreased or increased, to release a, locklng -lever and toallow part-s tio-return to normal position, so that any variation in load on the platform will lock the scale beam.

This invention further v consists in the novel details of construction shown and` described, and particularlypointed outin the claims.

In the drawings, lFigure 1 is a longitudi nal section of the base, :show-ing the auxiliary mounting of the platform and` the auxiliary system of levers in the position it occupies when there is no weight upon the platform. Fig. 2 is a section similar to Fig', 1 but showing the system of levers in the position it occupies when a weight is on the nary manner.

Fig. 9`is an end yiew of the parts-shown in Fig. 8, the casing being omitted. Fig. 10 is a plan of certain of the parts shown in Figs.

4 and 5. Fig` 11 is anend view of the same parts. Fig. 12 is a front elevation of part ofthe mechanism shown in Fig. 4 and Fig. 13 is a viewcorresponding to Fig.- 4 and Fig. 5, certain' of the part-s being removed. Fig. 14 is a section on 'the' line 14-14 of'Fig. 12, looking in the direction indicated by the arrows.y Fig. 15 is a front elevation of the machine on a greatly reduced scale.

Similar -characters of reference refer to ,like parts throughout; the several views.

The base 1 (Figs. 1, 2 and 3) has lugs 2 formed on its inner side that carry the pivots 3 upon whichthe main lever 4 lof the scale is supported by chairs 5 in the ordi- The secondary lever 6 is swung from pivots 7 in the lugs 2 at the 4other end of the baseby means of'chairs 8,

formed upon spider 10. lThe platformA 16" has downwardly extending lugs 21 that are adapted to contact with and rest directly upon s'pider 10 whenever the load on the platform is sufficient to overcome the strength of spring 19. The platform also has formed up-onitslower side a contacting face 22 for a purpose hereinafter pointed out. The spider 10 includes a bent longitudinally extending bar 30 upon which pivots 31 and 32 are mounted, and turning.

upon-these pivots are levers 33 and 34, respectively, whose adjacent ends are engaged with each other by a Y or slotted joint, as indicated at 35. The rear end ofthe lever 34 attaches to an auxiliary connecting rod 36 (having a laterally bent upper end 37, Fig. 11), and is normally drawn upwardly about pivot 32 by the tension spring 38 that is secured to the lug 39 on the spider 10. The same spring also holds the front end of the lever 33 in engagement with the contacting face 22 ofthe platform 16, previously referred to.

The pedestal 40, that together with the base 1 forms the frame of the scale, has supp-orted therein upon pivots 41 and 42, respectively, the main beam 43 and the balancing beam 44, that are connected in any desired manner, as by the link 45.' As soon as a load is placed upon platform 16, the main beam 43 is thrown up and held in the position shown by the dotted lines through the action of the auxiliary connecting rod 36 upon mechanism that will now be lpescribed. A f j supporting plate 50 maybe attached, by means of screws 51 orI otherwise, to the irregular inner surface of the head of the pedestal (Figs. 4 and 5.) which is indicated in dotted lines. This plate is provided with a pivot 52 and turning thereon is a lever in- The lever 53 comprises a rigid member 6()` having a projection 61 with which the laterally bent end 37 of the auxiliary connecting rod 36 is adapted to engage, asfshown in4 Fig. 4, the opposite end of the member 60 carrying'a pivot 62 about which a second.

vrigid member 63 is mounted to swing in a vertical plane. The member' 60 is provided with a seat 64, againstwhich a lug 65 o n the member 63 is adapted to contact, the lug and seat being normally held in ,engagement by the tension spring 66 that is secured to projections 67 and 68 on members 60 and 63, respectively. This spring is of such strength that the two parts 60 and 63 normally constitute a single operative member. The member l60 has rigidly secured thereto a downwardly extending arm 69 that is provided with a perforated lug 691, as shown rest against a stop 73, which are connected to a member 74 that is attached to the head of the pedestal in any desired manner at the left end of the opening therein (Fig. 8). This member 74 has` slots 75 formed therein within which the main scale beam 43 and the balancing beam 44 are adapted to vibrate vertically.

It will be seen that when a load is placed upon the scale platform, the auxiliary rod 36 is drawn downwardly and that it engages, when in the position shown in Fig. y4, with the projection 61 on member 60 and raises rod 54 to locking position. It will also be seen that, because of the spring connection between the members 60 and 63 of lever 53,

plate 50 is provided with the forwardly projecting bosses and 81, best shown in Fig. 10, to which a second plate 82 is secured, preferably by screws 83 and 84. Between the plates 80 and 81 a lever 85 having three arms 86, 87 and 88, (Figs. 12 and 13) is mounted to swing about the pivot 89, supported by the twoplates 50 and 82. The arm 86 has projecting from its front side a thumb-piece 49 (Figs. 10 and 11) that extends through a slot in the front face of the head of the pedestal, the'slot being closed by extensions 90 and 91 that may be formed integral with the arm 86, the latter being also provided with a rack 92 with which a full-stroke ratchet 93, pivoted at 94 in the plate 82, is adapted to engage. The ratchet is normally held in the position shown in Fig. 13 by a tension spring 95 that is secured to the plate 82 at 96. The arm 87 has `bifurcations 97 at its outer end; and the arm 88 has formed therewith a head 98 for a purpose hereinafter specified.` The arm 88 has secured thereto at' 99 a tension spring 100 (Fig. 12), the other end of which may be attached at 101 to the side 102 of a c oinguide, the spring normally holding the lever in the position shown in Fig. 12. The lever 53 has formed upon its front side a projection 110 that is normally engaged behind the head 98 (Fig. 12). The bifurcated end of the member 87 engages with a pin 111 on a sliding actuating bar 112, one end of which has forme therein a slot 113 that engages over a guide pin 114, projecting from the plate 50. The other end 115 ofthe sliding '(Figs. 12 and 14) o the plate 5G, an'd is spaced thereby from the side lof the coin guide 102 a distance greater than the thickness of a coin, by a tension spring 127 that is anchored to the plate 50 at 128 and is secured to the sliding plate at 129. The slid ing plate is extended laterally at 130 (Figs.

` 11 and 14) to form a guide for the rod 36 which is loosely secured therein by a plate 140, preferably connected to the sliding plate by a pin 141 and a screw 142. The side v102 ofthe coin guide has projecting therefrom a pin shaped guide member 143, and secured. to plate 50'by a screw 144, is a piece 145 having an inwardly projecting end 146 (Fig. 11) that extends through an opening in the plate 50, and forms a second guide member for a coin 147 that may be inserted in a slot 148 in the plate 50 between the cross-piece 102 and the. other side 125 of the coin guide. The cross-piece has a -downwardly project-ing end 149 (Fig. 11)

against which the coin is held by the end 115 of the actuating bar 112 whenevery the bar is moved to the right, as shown in Fig. 13.

It will be seen that the coin, when in the position just referred-to, constitutes a temporary connecting member between the actuating bar 112 and the sliding plate 120, the part'125 being connected thereto. Assuming the sliding plate to have been moved to the forward end of its stroke as indicated in dotted lines in Fig. 13, and there held and the actuating barwithdrawn, the coin will vfall into a coin chute of ordinary construction, shownin Fig. 12. The rack 92, heretofore referred to, is of a length just suiiicient to prevent the actuating bar from being withdrawn before'the end 'of its forward stroke, at the termination of which the ratchet 93 rides olf it and is thrown to neutral position by spring 95,y as indicated in Fig.` 13. The spring 100'then returns the three-armed lever to the locked position indicated in Fig. 12. The Vterm forward stroke signifies a movement to the right in Fig. 13. .K

The main connecting rod 9 has secured to its upper end a spri'ng 150 that is attached t6 a connecting member 151, `the details of which are 4shown in Figs. 4, 5, 6 and 7. This member is provided with a laterallyofset vertically projectingupper end 152, which has formed therein a seat 153 for a `knife edge on the` frame ofthe balancing beam 44, and with a perforated lug 154 having an arm 155 thereon, the' rod 9 passing through the'perfora-tion in the lug. It is further provided with an arm 156 (Fig. 6) and a seat 157, and with a slotted lower end 158, the upper limit of the slot being indicated at 159 in Fig.V 7.- The main connecting rod 9 has attached thereto, preferably by a set-screw 160, a block 161 having a downwardly extending arm 162, and a laterally extending projection 163 that is received by the guide slotfin the lower end of themember 151. j

The arm 156 supportsa pivot 165 upon which a lock-bar releasing lever 166 is mounted, the latter having a laterally turned end 168 and an upwardly extending arm 169, provided with a counterpoise 170. Pivotally suspended at y from lever 166 is a ratchet-bar 176 having a slot 177 in its lower end., A screw-threaded pin 178, mounted in' the arm 155, passes through the slot and guides the rack-bar in its vertical movement. Pivotally suspended from a point 179 on the opposite side of the pivot 165 of the lock-bar releasing lever is a second ratchet-bar 180 having a slot 181 in its lower end. A. screw-threaded piny 182, mounted in arm 162 and extending through the slot, guides this rack-bar in its vertical movement. The weight of the counterpoise 170 is` suiiicient to normally cause the lock releasing lever to rest on the seat 15.7.

The end of the releasing lever 166 is adapted to contact with the end 183 of a pivoted locking bar 184 that is mounted to swing verticallyon the plate 50 at 185. The

sliding plate 120 has formed thereon an abutment 186, and the locking bar,has a shoulder 187, on its under side, that. is adapted to fall behind the abutment and hold the sliding plate in the position indicated in Fig. 5. The locking bar also has an inclined lower surface 188 that is adapted to contact with and rest -upon the plate 140 when thel parts are in the position shown inlFig. 4..

Mounted upon pins 190 and 191, screwthreaded in the'block 161, are the dogs 192 and 193, that are adapted to engage respectively with the ratchet-bars 176 and 180.

lThese dogs are provided with .counterpoises 196 and' 197, respectively; and are further provided with inter-engag ing lugsI 198 and 199 by means of which any tendency ofthe dog 192 to turn in a counter-clockwise direction about its pivot (Fig. 6) is transmitted to dog 191, .to-

cause the sameto-turn in afclockwise direction about its pivot. The .dog 192 has formed'vthereon a perforatedprojection A2,00,

and secured to this perforated projection is one end of a wire`201, the other end of which is passed through' the perforation in the lug 691 on the bar 69 (shown in Fig. 11)' and is bent as shown at 202 in Fig. 4. The dog 19,2 is loosely embraced by the `lateraland freeing the scale bars.

projections 210 and 211 on a bar 212 (Figs. 5 and 10) that may be adjustably secured to the sliding plate 120 by the pin-and-slot connections 213.

Operation: The rststep in the operation of this scale is that of locking the scale beams in position. lVhen'ever a load, suiiicient to overcome the strength of the spring 19, is placed upon the platform, the latter sinks about -its pivots 14 until the lugs 21 contact with the spider 10. Through the action of thelevers 33 and 34, the auxiliary connecting rod 36 is pulled downwardly so that its bent upper end 37 engages with the end 61 of lever 5 3 in the head of the pedestal and turns the latter about its pivot 52. The seat 55 on the other end of the lever is thereby carried upwardly, and, with it, the locking rod 54, the bent portion 70 of which engages with the under side of the1 main beam 43 and prevents the beams from swinging freely. It will be seen that the swinging of the lever 53 raises the pin 1'10 thereon out of the path of the head 98 of the three-armed lever as shown in Fig. 13, and that the latter may then be turned about the pivot 89 by pressure applied to the thumb-piece 49. Any turning of the threearmed lever, however, produces no effect upon the locking rod 54 until-a coin 147 is inserted in the coin guide for the reason that, without the connecting coin, the end 115 of the actuating bar slides idly in the slot 116, and does not affect the sliding plate 12.0. The next step is the insertion offa coin 147, which falls through the slot 148 in the plate 82 into the position shown in Fig. 11. Upon pressure now being applied to the thumb-piece 49, the actuating bar 112 carries the coin forward, that is, to the right in Fig. 13, and, with it, because of its contact with cross-piece 125, the sliding plate 120, until the plate 140 has lpassed from engage'- m-ent with the inclinedsurface 188 on the on the sliding plate 120, whereby the latteris held in the position shown in Fig. 5, and

with its end 183 in the path of the end of the releasing lever 166. At the same time, due to the'fact that the auxiliary connecting rod 36 is embraced by the plate 140, its upper end 37 is swept to the right in Fig. 5 out of the path of the end 61 of the lever 53, which then swings counter-clockwise on the pivot 52, 'thus allowing the locking rod 54 to fall Therefore, the locking rod 54 cannot free the beams until a load is on the platform and a coin has been inserted. Any load on the platformv sufficient to overcome the tension of the spring 19, under the platform, may be divided into two parts, one of which raises the locking' rod 54 in the manner described.

connecting rod 9 to spring 150 and causes an elongation thereof, as indicated in Fig. 5. This draws the block 161 downwardly in respect to the member 151, and thereby lowers the ratchets 192 and 193 in respect to the teeth on the corresponding ratchet bars 176 and 180. It is apparent that any diminutionof the Weight of the load upon the platform, after the ratchets are engaged with the ratchet-bars, will cause a shortening of spring 150, and will, by means of ratchet 19,2 and ratchet-bar 176, elevate the counterweighted end of lever 166 and cause it to engage with the end 183 of the locking bar 184, thereby releasing the bar from engagement with the sliding plate, which will instantly return to normal position, and at the same time return the end 37 of rod 36 to position over the end 61 of lever 53. `On the other hand, it is also apparent that any increase in the load upon the platform, after the ratchets are engaged with the ratchet-bars, will cause a further lengthening of the spring 150, and will, by means bf ratchet 193 and ratchet-bar 180, elevate the counterweighted `end of the lever 166 and cause it to engage with and release the locking bar.

as before. In either case, the rengagement of the auxiliary connecting rod 36 with the lever 53 immediately raises the locking rod 54 into contact with the scale beam. Thus there is provided a device whereby any increase or diminution of the weight on the platform, after the ratchets are engaged with the ratchet-bars, is utilized to instantly lock t-he vscale beam, and to prevent further weighing until after the insertion of a second coin. Theratchets ar'e held from engagement with the ratchet-bars and an stripping of the teeth from the bars which might be caused by vibration of tl'ie platform as a person ,steps on or off, is prevented bythe wire 201. As the sliding plate 120 moves from the position shown in Fig. 4 to that shown in Fig. 5, -carrying with it the rod 36, the upper end of this rod contacts with the end of lever 166 and pushes the member 151 a slight distance to the right in contacts with the shoulder-187 on the locking bar 184, and the member 151 swings very slightly in ya clockwise direction (Fig. 5)n about its seat on the frame of the scale beam, which causes engagement of the At the same time, the projection ratchet-bar 176 with the lratchet 192. Because of the interengaging lugs 198 and 199, the ratchet 198 is held from engagement with the ratchet-bar4 180 during the time in which ratchet 192 is held away from the ratchet-bar 176, and is allowed to be engaged with its ratchet-bar by the action of the counterpoise 197 Whenever. the ratchet- 192 is engaged with the ratchet-bar 176.

It is evident that many changes may be made in the described device by those skilled in the art without departing from the spirit of my invention.
